I'm not going to relitigate the nebulous allegations that his critics always distract with.

I listened to the YT clip. It was very "When did you stop beating your wife?"

I don't know the context, but Josh uses the term "pedo" pretty loosely considering the weirdos his site mocks & archives.

If I had to guess, I'd speculate Null was referring to loli enjoyers on 8chan.

He has a huge disdain for those types even if it technically isn't illegal like he mentions in the clip.
